Figure 2 Hippocampus in normal aging and Alzheimer disease (AD)

Illustrated for comparison are cross-sections through the right hippocampus at the level of the red nucleus in a normal control (NC) and a subject with mild AD, obtained using a 7-T gradient-recalled echo sequence. The scale bar is 1 mm. DG = dentate gyrus; SP = stratum pyramidale; so = stratum oriens; SRLM = stratum radiatum/stratum lacunosum-moleculare; sub = subiculum.
